I am seeing the Spiderman Kingpin BAF wave hit in my area which is Northeast Texas. I saw Puma and Blackcat sitting on some pegs at Walmart and Red Goblin at Gamestop. Plus Captain Marvel figures peg warming like crazy along with Black Panther wave 2.

I remember when Rogue was pegwarming really hard in my area at my local Walmart stores. They had to throw her on clearance just to get rid of her, Jean Grey and Kitty Pride. I wished I grabbed some of those to help ya'll out but I left them there thinking I would let someone that needed them a chance to find them.

Speculating off the top of my head:
X-Men related:
Some X-Men reveals like last time,
1.) Jim Lee Storm if we do not get her this year. ( I expect a running change like we got with Psylocke with a sliver version and a white version.) I am going off the teaser question from the last SDCC of which color do we want her painted.
2.) Emma Frost in her classic white uniform maybe if we do get Storm this year. (With the way they are doing females now days I don't know if we will ever get her the way we want.)
3.) Some villain maybe Lady Deathstrike or something. It depends on where we get Storm.
4.) Some obscure character.
Spiderman related:
1.) Classic Vulture (He's due and his chances are pretty high of popping up).
2.) Blade in trenchcoat (Huge guess on my part and we are due for another Spidey ally hero to pop up.)
3.) Member of New Warriors (One of them is due to show up.) or Life Foundation (one of them is really due to show up.) We might get both figures from each group.
Vintage Wave:
I want another Homerun like we got in wave two.
Dr. Doom (Classic)
Falcon (If we get Classic Vulture then I suspect Falcon to pop up.)
Dr. Strange (80's uniform)
Just some of my guesses.

I also got to thinking that they might do a tribute to Stan Lee with his passing not too long ago. First Appearance Spiderman, First Appearance Hulk (Grey reusing the Hulk from the upcoming two pack), Stan Lee figure (I don't know if they can do this or not legally), Classic Dr. Doom, and Classic Dr. Strange (First Appearance look or 80's uniform). Slap the 80's Anniversary label on it.
This would be a nice tribute and a highly sought after collecter's set.

My want list is nearing completion. All that remains is:
Banshee
Longshot
Rachel Grey
Pyro
Avalanche
I would love to see them finish off the Outback team and the Giant Size team that first appeared in the mid 70s. Maybe a classic Shadowcat in her blue 80s outfit.
